IMPROVEMENT IN WRlNGlNG-MACHINES.

Specification forming part of Letters Patent No. 121,589, dated December5, 1871.

To all whom it may concern:

Be it known that I, JAMES M. CLARK, of Lancaster, in the county ofLancaster and State of Pennsylvania, have invented a new and usefulImprovement in wringing-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the same, reference beinghad to the accompanying drawing making a part of this specification.

This machine consists of a pair of rubber rollers ot'oommonconstruction, the journals of which are supported and guided at each endwithin an open slot in a simple metallic frame. Upon the journals of theupper roller are pulleys, over which are drawn gum-elastic bands, whichalso pass over the projecting ends of an adjustingbar located under thelower roller, and connected to the frame by adjusting-screws, so thatthe upper roller may be drawn against the lower one with any necessaryforce.

In the drawing, Fig. l is a front elevation of my improvedwringingmachine. Fig. 2 is an end View of the same. Fig. 3 is a sectionthereof at the line as, fig. 1.

A represents a metallic frame containing an adjustable bar, B, the endsof which project through slots a a in said frame. C C are clamps ofcommon construction, for attaching the machine to a wash-tub. In theupper part of the frame A are open slots at, containing the shafts d eof the rollers D E. These rollers may be of commonform, but arepreferably made on winged On the projecting ends or journals of theupper roller-shaft d are pulleys F, to receive gumelastic bands G whichalso pass aroundheads or pulleys H on the ends of the adjusting-bar B.It is immaterial whether the heads 11 turn or not, as the journals dturn freely within the pulleys F. This involves much less friction thanif the bands Gr were required to run. The bar B is connected, bythumb-screws I, with the lower partof the frame, so that by drawing thesaid bar down any necessary pressure may be produced between therollers; but this press ure is sclt regulating, owing to the elasticityof the bands G, so that thick articles passing between the rollers willseparate them to a greater extent and will at the same time be subjectedto heavier pressure. The rollers may be driven by a crank, J, or, it my\vringer be used in connection with my washing-machine patent-ed Augustl, 1571, the driving-shaft c of the rollers may, with good advantage, begeared to a "ertical shaft, which will derive rotation from theworking-shaft of said washing-machine.

I claim as my invention- The Wringing-machine herein described,consisting of the frame A a a, rollers D E, pulleys F, elastic bands G,bar B, connecting-heads H, and adjusting-screws I, all constructed andcombined to operate substantially as and for the purpose set forth.
